john deere 440 muffler

[thumper]

ive been using a long glasspack muffler on this 440a since ive owned it.   could this muffler be hurting me.?  ive read members statements about them not working on a detroit.. ??? :

yup it sure can.........when the forrest service see's it. must have a spark arester unless its toubro charged.

I would say a glasspack on a detroit could definitely hurt you.  Well, unless you're a mile away, wearing ear plugs, ear muffs, and ear muffs on your ear muffs, then you're probably mostly safe.

 Some 4 stroke diesel motors require back pressure to get there Peek hp and John Deere might be one, that would be my concern.

I ran straight pipe on my Detroit's, the more air you can suck in, and the faster you get ride of it the more power you have with a 2 stroke diesel, and a 2 & 4 stroke gas.

run my 440 straight piped, no issues yet and it's been that way for the last 20 years my family has owned it

There's no way I'd run a Detroit with a straight pipe, I don't think the power gain could be worth it Detroit just sound too ugly.
